The value of "size" comes from the user. When we add "start + size"
it could lead to an integer overflow bug.
It means we vmalloc() a lot more memory than we had intended. I believe
that on 64 bit systems vmalloc() can succeed even if we ask it to
allocate huge 4GB buffers. So we would get memory corruption and likely
a crash when we call ha->isp_ops->write_optrom() and ->read_optrom().
Only root can trigger this bug.
